Definitions
- the present invention is in the field of polyurethanes. It relates in particular to flexible polyurethane systems and to a process for the preparation of such polyurethane systems using certain crosslinkers to increase the hardness.
- Polyurethanes of various types are usually prepared by the polymerization of diisocyanates, such as. As 4,4'-methylenebis (phenyl isocyanate), short MDI, or 2,4-toluene diisocyanate, TDI short, prepared with polyether polyols or polyester polyols.
- Polyether polyols can e.g. be prepared by alkoxylation of polyhydroxy starters. Common starters are z.
- glycols glycerol, trimethylolpropane, pentaerythritol, sorbitol or sucrose.
- additional blowing agents are commonly employed, such as e.g.
- Pentane methylene chloride, acetone or carbon dioxide.
- the chemical blowing agent used is usually water, which reacts with elimination of carbon dioxide with isocyanate to form a polyurea.
- surface-active substances in particular silicone surfactants, are used to stabilize the polyurethane foam.
- Polyurethane foams or foams are used in a wide variety of fields due to their excellent mechanical and physical properties.
- a particularly important market for various types of PU foams such as conventional ether and ester polyol based flexible foams, cold foams (often referred to as HR foams), rigid foams, integral foams and microcellular foams, as well as foams whose properties lie between these classifications, such , B. semi-rigid systems, represents the automotive and furniture industry.
- HR foams cold foams
- integral foams and microcellular foams as well as foams whose properties lie between these classifications, such , B. semi-rigid systems, represents the automotive and furniture industry.
- Other relevant polyurethane systems are for. Polyurethane coatings, polyurethane adhesives, polyurethane sealants or polyurethane elastomers.
- the market is demanding ways to increase the hardness of flexible polyurethane foams.
- a mattress or a chair is the more comfortable the harder it is.
- an increase in hardness is generally not readily possible, at least not without a mostly unwanted change in other physical properties of the mattress or chair to accept.
- the hardness can be determined either as a so-called compression hardness according to DIN EN ISO 3386-1: 1997 + A1: 2010 or as an indentation hardness according to DIN EN ISO 2439: 2008.
- the compressive strength a square specimen is compressed between two plates and the force required to compress this specimen to a certain amount of its original height (eg 25%, 40% or 65%) is measured. This value is then related to the tested area and the compression hardness or the compression resistance of the foam in kPa is obtained.
- the indentation hardness or compression resistance is determined with smaller pressure plates, which are rounded off to avoid excessive shear. In this case, the foam is compressed by 25%, 40% and 65% of the initial thickness, and then the indentation hardness or compression resistance is expressed in N.
- polyurethane foams of increased density also have increased compression hardness.
- the disadvantage of this is that for the production of foams of increased volume weight, a larger amount of raw materials is needed, which makes the production of foams less economical.
- the use of polymer polyol such as SAN, PHD or PIPA polyols also leads to a significant increase in hardness of the foams.
- the polyether polyol required for the production of the flexible foam is partially replaced by polymer polyol.
- a smaller amount of polymer polyol used here only leads to a lower increase in hardness.
- a use of less than 10 wt .-% thus leads to a negligible increase in hardness, so depending on the polymer content in the polymer polyol and desired degree of hardness of the polyurethane foam usually between 10 and 100 wt .-% of the polyether polyol required for the production of the foam replaced by polymer polyol. Since the price of the required polymer polyol usually exceeds the price of the standard polyether polyol very much, this method has the disadvantage that it is very expensive. Flexible polyurethane foams with improved hardness can thus only be presented with considerable financial overhead.
- polyurethane foams prepared with styrene / acrylonitrile (SAN) copolymer polyol, usually have a poor emission behavior, for example, determined according to the test chamber method based on the DIN standard DIN EN ISO 16000-9: 2008-04, 24 hours after strigcroadung.
- Further disadvantages of the method described above are also the increase in the density of the polyurethane foam induced by the polymer fraction in the polyol and the poor availability of polymer polyol in certain regions of the world.
- One way to increase the hardness of a flexible polyurethane foam at constant density is to increase the degree of crosslinking in the foam network. This can in turn be achieved by various measures. First, it is possible to increase the isocyanate index.
- the isocyanate index is a well-established index in the field of polyurethanes and describes the ratio of actually used isocyanate to isocyanate (calculated for a stoichiometric reaction with polyol, water and other isocyanate-reactive compounds) multiplied by 100.
- An index of 100 stands for a molar ratio of the reactive groups of 1 to 1.
- the characteristic number for the production of soft block foam is normally between 95 and 1 15, viscoelastic foams are also below.
- An increase in the index however, can have several serious disadvantages in addition to the desired increase in hardness. Thus, increasing the degree of crosslinking generally results in lower air permeability or increased closed cell foam.
- an increased amount of isocyanate has the disadvantage that the exotherm of the foaming process is increased and thus a higher core temperature is achieved in the foam. This can lead to core discoloration (so-called “scorch”) or, in extreme cases, to spontaneous spontaneous combustion of the foam block.A greater amount of isocyanate also always means a financial extra expenditure for the foaming agent.An undesirably increased closed-cell density is also obtained if for better crosslinking and thus A further possibility for increasing the crosslinking and thus increasing the hardness of the flexible foam is the use of crosslinking agents (so-called “crosslinkers”). Crosslinkers are additives which usually represent highly functional isocyanate-reactive compounds.
- TDI-65 is a mixture of 65% 2,4-toluene diisocyanate and 35% 2,6-toluene diisocyanate.
- High closed-cell density is undesirable in mattresses and upholstery for several reasons. Due to a high proportion of closed cells, a mattress loses a large part of the respiratory activity, ie water can not be absorbed by the mattress and thus not be transported away. At night, the human body releases moisture into the environment in the form of sweat and / or welding fume (at least about 0.7 L of water per night depending on the climatic environment). To prevent sweating, it is therefore very important that the materials of the mattress can diffuse and / or dissipate the liquid and / or evaporations and thus lead away from the body. This creates a dry and comfortable bed climate.
- foams with increased closed cell content have a reduced elasticity, which in turn can have a negative effect on the comfort of a chair.
- the concrete problem to be solved by the present invention was to provide additives which allow easy access to polyurethane systems, preferably polyurethane foams, in particular freed-up polyurethane soft block foams or molded foams with improved hardness and sufficient open-patency.
- Adequate open-celledness is understood in particular to mean that the gas permeability of the polyurethane foam according to the invention is preferably from 1 to 300 mm of water, preferably from 3 to 250 mm, based on DIN EN ISO 4638: 1993-07.
- (ii) has an average hydroxyl number, determined in accordance with DIN 53240-1: 2013-06, of 110-1080 mg KOH / g, preferably 120-250 mg KOH / g, and
- additive comprises an additive composition which may contain at least one compound (V) as described above, in which case the entire additive may comprise precisely one such compound, the entire additive may consist precisely of such a compound.
- the entire additive may comprise a plurality of different such compounds (V), the entire additive may consist of several different such compounds (V)
- the additive may comprise further components, in particular one or more inorganic or organic solvents, preferably selected from water, alcohols, in particular polyether monools or polyols, preferably consisting of H-functional starter substances to which by means of alkoxylation alkylene oxides (epoxides) having 2-24 carbon atoms, preferably ethylene oxide and / or propylene oxide, have been attached and which have a molecular weight of preferably 200 - 8000 g / mol before at from 300 to 5000 g / mol, more preferably from 500 to 1000 g / mol, and a PO content of preferably 10 to 100 wt.%, Preferably from 30 to 100 wt.%
- epoxides alkoxylation alkylene oxides
- a PO content preferably 10 to 100 wt.%
- An inventive additive comprising inorganic and / or organic solvents corresponds to a particularly preferred embodiment of the invention.
- the article according to the invention enables the surprisingly simple provision of polyurethane foam with improved, preferably particularly high hardness and sufficient open-patency.
- the improvement in hardness refers to the comparison with polyurethane foams prepared without the additive of the invention but otherwise in an analogous manner.
- the provision of particularly high-quality foams with good, stable and homogeneous foam structure is made possible.
- the resulting foams show as a further advantage favorable, so fire or flame retardant, fire properties in case of fire and have improved aging properties. To investigate the aging properties, a method based on ISO 3385-1975 was developed and carried out.
- a foam pattern was compressed 80000 times to 70% of its original height and the loss of thickness and hardness determined (detailed description in the examples). It is also advantageous that can be used in the provision of the polyurethane foam on the usual production equipment. Yet further advantages of the invention are that the additives according to the invention are easy to handle, in particular have a low viscosity and are advantageously stable to hydrolysis, low in emissions and virtually odorless. They have a wide processing play and can be produced reproducibly by standard methods. The use of the additive according to the invention does not lead to any disadvantageous effects on the physical properties of the foam. In particular, tensile strength, compression set, expansion of the foam are not impaired.
- the foam obtainable according to the invention is advantageously distinguished by an application-suitable gas permeability (A), density (B), pore structure (C), compressive stress or compression hardness (D) and cell structure (E).
